Two six-foot-long barracuda appeared and circled around two divers for several minutes during a scuba dive in the Cayman Islands. They passed within inches of them several times, moving closer on each pass. With their menacing looking teeth and angry looking eyes, these huge fish are very intimidating. This is even more true when there are two of them! Such behavior is usually because of curiosity and not aggression, but this experience was hair-raising for the divers.
